Be it known that I, WILLIAM A. BOYDEN, of Altoona, in the county ofBlair, and State of Pennsylvania,

have invented a new and useful Improvement in Axle-Boxes;' and I dohereby declare that the following is a full, clear, and exactdescription of the saine, reference being had to the accompanyingdrawings, making a portion of this specification, in whieh- Figure 1 isa side viewof an axlelbox constructed according to my invention, withone side of the case removed to show the internal parts.

Figure 2, a central vertical longitudinal section of the same.

Figure 3, a transverse vertical section ofthe same, taken in the line xx, of figs. I and 2.

Similar letters of reference indicate corresponding parts in all thefigures.

The object of this invention is to provide an eilicient meanswhereby theescape of lubricating material from the journals of car or other axlesmay be provided against, and the invention consists in two semicircularpacking-plates, formed with rebated ends, and furnished with suitablepressure-springs, and so'combined with au annular washer and with thejournal and the bearing of the journal-box, as to effectually secure theresult desired. i

To enable others to understand the nature and construction of myinvention, I will proceed to describe it with reference to the drawings.

A represents the box or easing of the apparatus, in which thelubricating material is placed. The cylindrical end portion of the c'aror other axle is shown at B, the said end passing into the case Athrougha suitable circular hole in the outermost end ofthe said ease, andhaving the journal a formed thereon, made of a somewhatreduced'diameter, and itting into the under side of the bearing @securedin the upper part of the casing A aforesaid, and constituting a portionof the axle-box, of which such oase forms the other part. Fitted uponthe axle B, within the case A and near the outer end of the journal a,are two semicircular washer-plates, (l, which are placed one upon theupper, the other upon the low-er side of such part of the axle, and areeach rebated at their two ends, in such manner that lips or tongues care formed thereon, the lips-upon one ofthe aforesaid washer-plateslapping past or upon those of the other, in such manner as to break thejoints where the ends of v.

the two plates are broughttogethei, as indicated more fully in' fig. 1.Each of the aforesaid plates is furthermore provided with a verticalstem, e, which projects into a cylindrical recess or socket, j',provided in the adjacent side of the case A, the said stems beingsurrounded by spiral springsg, which press the plates()` inward, withtheir inner surfaces in snugcontact with the cylindrical portion of theaxle upon which the said plates are situated, as just hereinbefore setforth. Placed around the axle, between theplatesC and the contiguous endof the case A, is an annular washer, D, which may be oi' leather, orequivalent material. The plates C are kept in snug contact with thewasher D by vertical partition-plates mformed transversely upon the topand bottom of the case. v

The case A has, of course, a suitable quantity of lubricating materialplaced thereinwhich lubrieates the journal a to the required degree, theaforesaid lubricating material being prevented from escaping or workingout from the case A around the cylindrical portion of the axle by thepacking-plates C, pressed closely thereon by the springs g, and theleakage of the said lubricant, at the junction of the extremities of theaforesaid plates,

being guarded against by the lapping-past each other of the lips e, leftupon the said extremities by rebating` the same, as hereinbefore setforth. The washer D, by forming a close packing between the plates justmentioned and the contiguous end of the ease A, prevents the outwardpassage of any. portion of the lubricant that may l nd its way above orbelow the packing-plates, thelubricant being by these means ei'ectuallyretained within the case A, thereby securing its most ciiicient andconomical action in lubricating vthe journal. y

What I claim as my invention, and desire to secure by Letters Patent,is- The two semicircular packing-plates C, constructed with rebatedends, and furnished with springs g, in combination with the annularwasher D, the journal a, and the bearing b of the axle-box,substantially as and for the purpose herein set forth. l l
